Getting the most out of stock Power Steering

What does it take to get the most out of your stock power steering pump and box?

Iím trying to turn 35s at 10lbs and needless to say Iím having troubles, and the mini spool isnít helping.

The only article I have found is this
turn up the pressure on power steering pump. - Pirate4x4.Com Bulletin Board


Iím sure some of you have some secrets, you're willing to share

Really no one has tried a overdrive pulley, or found a way to make more pressure at lower rpm?

I have a saginaw style pump in my YJ, and i did a mod that modified the spring and drilled out the fitting. It seems to have helped a little, but i really haven't driven it that much to know if it really did a lot.

^^^That’s a nice write up

Anyone done this and have enough seat time to determine if it was worth it?

It only takes like an hour to do and a bottle of PS fluid go for it!.

The guys who are recommending it build full hydro, and hydro assist set-ups, and they feel it's worth it.

LOL just be selective on the size of bit you use.
I found a bit the same diameter and went up slightly less than 1/8" they recommend.

I did this mod 6 years ago, and haven't any issues.

I just tried this mod, and now I don’t have any power steering. It worked really well at first and then it just quit. I also added a cooler while doing this, it shouldn't affect anything. Also I don’t see any leaks.

Any Ideas?

Thanks

Either the relief valve got fuxored somehow, or something is blocking fluid flow.

But Ill give it another try once I get my new pump on.

well mileage and 35" tall tires plus spool most likely did it but shim may have helped
did sliders fall off yet buy the way

haha Iím sure it didn't help any, but it sheared the shaft that the pulley rides on in two. It was a clean break, not sure if I blocked off all of the flow and that caused extra pressure on the on the pump, or what happened.

And the sliders havenít fallen off yet Their still not painted tho : ( the weather just hasn't been good enough. But Iíll be sure to let you know how they do at R&V in 2 weeks. Thanks again for the help

Yeah Iím sure mileage had something to do with it, but for it to happen right after I did this seems odd. It sheared within one minute after the mod. Then the pulley slid out and knocked the belt off while I was driving. I guess Iím just unlucky
